Product details
Overview
ADC102S101CIMM/NOPB from Texas Instruments is a 10-bit, dual-channel successive-approximation ADC with serial SPI-compatible interface, 500 ksps to 1 Msps sample rate range, ±0.16 LSB typical DNL, and 61.7 dB typical SNR. It operates from a single 2.7V–5.25V supply and delivers 3.9 mW typical power consumption at 3V - used in portable instrumentation for simultaneous analog signal digitization.
For engineers reviewing the ADC102S101CIMM/NOPB datasheet, ADC102S101CIMM/NOPB pinout, ADC102S101CIMM/NOPB application, or ADC102S101CIMM/NOPB equivalent, key selection criteria include guaranteed no-missing-codes performance over industrial temperature (−40°C to +85°C), channel-to-channel crosstalk of −78 dB, and configurable input channel selection via DIN-controlled control register.
Technical Context
The ADC102S101CIMM/NOPB implements a charge-redistribution SAR architecture with internal track-and-hold, supporting either single- or dual-input acquisition. Its conversion timing is tightly synchronized to SCLK, requiring exactly 13 SCLK cycles for conversion after 3-cycle acquisition, yielding a fixed 16-SCLK throughput time per frame.
Serial communication uses MSB-first straight binary output on DOUT, with DIN accepting 8-bit control words to select IN1 or IN2 for the next conversion. The device enters low-power shutdown (<0.47 µW at 5V) automatically when CS is high, eliminating external power management circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit with guaranteed no missing codes - ensures monotonicity and full code coverage across operating range. |
| Sample Rate Range | 500 ksps to 1 Msps - supports flexible system-level timing without requalification at different throughput points. |
| DNL / INL | +0.26/−0.16 LSB typ / +0.4/−0.1 LSB typ - enables accurate DC measurement and low-gain sensor interfacing. |
| SNR | 61.7 dB typ at 40.3 kHz - sufficient for 9.9 ENOB in medium-bandwidth industrial sensing applications. |
| Power Consumption | 3.9 mW typ at 3V / 11.4 mW typ at 5V - enables battery-powered operation with minimal thermal impact in compact layouts. |
| Supply Voltage | 2.7V to 5.25V single supply - simplifies power design by eliminating separate analog/digital rails. |
| Channel Crosstalk | −78 dB at 5.25V - allows independent high-fidelity sampling of two analog signals without mutual interference. |
Pinout & Package
ADC102S101CIMM/NOPB is housed in an 8-lead VSSOP (DGK) package with 0.65 mm lead pitch, optimized for space-constrained PCBs and compatible with standard surface-mount reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Falling edge initiates conversion frame; high state enables automatic shutdown and tri-states DOUT. |
| SCLK | Serial Clock Input | Directly controls acquisition (first 3 edges), conversion (next 13 edges), and data timing - no internal clock generation required. |
| DOUT | Digital Output | MSB-first serial data stream; active only during CS low; tri-stated when CS high. |
| DIN | Digital Input | Accepts 8-bit control word on first 8 rising SCLK edges to select IN1 or IN2 for next conversion. |
| IN1 / IN2 | Analog Inputs | Single-ended inputs referenced to VA; each accepts 0V to VA range with 33 pF input capacitance in track mode. |
| VA | Analog Supply | Primary power and reference rail; requires local 1 µF + 0.1 µF bypassing within 1 cm to maintain SNR performance. |
| GND | Analog Ground | Common return for analog and digital sections; must be connected to low-impedance system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Full specification across 500 ksps–1 Msps | Eliminates need for multiple speed-binned parts - one BOM item covers variable throughput requirements. |
| Channel-selectable dual-input architecture | Reduces component count vs. two single-channel ADCs; avoids inter-channel skew in time-critical sampling. |
| Automatic power-down on CS high | Reduces idle power to sub-µW level without external logic - critical for intermittent-sampling portable systems. |
| Straight binary SPI-compatible output | Direct interface to TI C2000, ARM Cortex-M, and FPGA soft peripherals without format translation logic. |
| Industrial temperature range (−40°C to +85°C) | Validated operation in harsh environments including motor control enclosures and remote telemetry nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC102S051CIMM/NOPB | Same 10-bit resolution and pinout, but specified for 200–500 ksps range only - lower max sample rate and reduced AC performance at 1 Msps. | Best suited for cost-sensitive, lower-throughput systems where 500 ksps suffices and 1 Msps headroom is unnecessary. | Select ADC102S051CIMM/NOPB only if system maximum sample rate is ≤500 ksps and SNR >60 dB is not required at full scale. |
| ADC122S101CIMM/NOPB | 12-bit resolution, same 500 ksps–1 Msps range and pin-compatible footprint - adds 2 extra bits but increases power to 5.2 mW (3V) and reduces SNR to 69.5 dB. | Preferred when higher resolution is mandatory for low-amplitude signal detection, accepting trade-offs in power and noise floor. | Choose ADC122S101CIMM/NOPB when application demands ≥12-bit effective resolution and can accommodate higher supply current. |
Compared with ADC102S051CIMM/NOPB, the ADC102S101CIMM/NOPB provides verified 1 Msps operation and superior dynamic performance; versus ADC122S101CIMM/NOPB, it trades 2 bits of resolution for lower power and better SNR efficiency in 10-bit use cases.

FAQ
What is the absolute maximum analog input voltage for ADC102S101CIMM/NOPB?
The absolute maximum analog input voltage for ADC102S101CIMM/NOPB is VA (analog supply voltage), with a hard limit of −0.3V to VA + 0.3V relative to GND. Exceeding VA risks damage or latch-up; inputs must remain within 0V to VA under normal operation per the datasheet's Analog Input Voltage specification.
Does ADC102S101CIMM/NOPB require external reference voltage?
No, ADC102S101CIMM/NOPB uses its VA supply pin as the internal reference - no external reference is needed. The LSB value equals VA/1024, so supply noise directly impacts accuracy; TI recommends local 1 µF + 0.1 µF bypassing within 1 cm of the VA pin to maintain specified SNR and INL performance.
How does ADC102S101CIMM/NOPB handle channel selection between IN1 and IN2?
ADC102S101CIMM/NOPB selects the input channel for the *next* conversion via an 8-bit control register loaded on DIN during the first 8 rising edges of SCLK after CS falls. Bits ADD1 and ADD0 determine selection: '00' = IN1 (default), '01' = IN2; '1x' is invalid and yields indeterminate DOUT.
What is the minimum SCLK frequency required for reliable operation of ADC102S101CIMM/NOPB?
The minimum SCLK frequency for guaranteed electrical performance is 50 kHz, per the Operating Ratings table. While the device may function below this, TI specifies timing parameters (e.g., tCSU, tCLH, tACC) only for fSCLK ≥ 50 kHz - designs targeting 500 ksps–1 Msps should use 8–16 MHz for optimal AC performance and timing margin.
Is ADC102S101CIMM/NOPB RoHS-compliant and lead-free?
Yes, ADC102S101CIMM/NOPB carries the /NOPB suffix, indicating lead-free (Pb-free) packaging and RoHS compliance per TI's environmental standards. The VSSOP (DGK) package uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 2a for standard SMT assembly.
